Ive been a flight simmer onboard FS9 for a while now. My question is how to separate AI "packs." Such as this, All of my current AI includes WOAI and PAI packages. However I am creating my own classic environment with TWA, Pan Am, etc. I am just wondering what the easiest solution would be to "turn off" the current airline environment (WOAI and PAI) and "turn on" the classic airlines?

I think the easiest way to make the switch is by using a batch file to rename files. Then you could have 2 batch files, each of them working by renaming the traffic*.bgl files to something like traffic*.moden or traffic*.classic and in turn renaming the deactivated files traffic*.bgl
